John Allison, who for two decades served as chairman and CEO of BB&T, the nation's 10th largest bank, told CNSNews.com it is a “mathematical certainty” that the United States government will go bankrupt unless it dramatically changes its fiscal direction.

Allison likened what he sees as the predictable future bankruptcy of the United States to the problems at Fannie Mae and Freddie Mac, whose insolvency he also said was foreseeable to those who studied their business practices and financial situation.

“I think the first thing we have to realize is where we’re going and to face it objectively,” Allison told CNSNews.com, when asked about the trillion-dollar-plus deficits the federal government has run for three straight years, the more than $13 trillion in federal debt, and the $61.9 trillion long-term shortfall the government faces (according to the analysis of the Peter G. Peterson Foundation) if the government is to pay all the benefits it has promised through entitlement programs.

“If you run the numbers, on all those numbers that you just talked about, which I think are accurate, very accurate, in 20 or 25 years, the United States goes bankrupt,” said Allison. “It’s a mathematical certainty."
